Taz1 is a hybrid receptor, in which the periplasmic receptor domain of Tar, an aspartate chemoreceptor, is fused with the cytoplasmic signaling domain of EnvZ, an osmosensor. Taz1 is able to induce ompC-lacZ expression in response to aspartate added to the medium. We introduced amino acid substitution mutations in the highly conserved region of the(More)
Taz1-1 is Tar-EnvZ chimeric receptor that is able to induce ompC-lacZ expression in response to aspartate. Previous studies indicated that aspartate binding to the receptor domain of the Taz1-1 receptor modulated the ratio of kinase and phosphatase activities of the cytoplasmic signaling domain. The 80-residue segment of chemoreceptors that is located(More)
As tumor development relies on a coordination of angiogenesis and tumor growth, an efficient antitumor strategy should target both the tumor and its associated vessels. Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) induces apoptosis in a tumor-selective manner. Additionally, thrombospondin-1, a naturally occurring inhibitor of(More)
Osmoregulation of the porin genes, ompF and ompC of Escherichia coli, occurs at the level of transcription through the action of EnvZ and OmpR proteins as well as at the level of translation through micF antisense RNA. In this study, we used a genetic screening approach to identify new genes which interfere with the expression of ompC or ompF. Using an E.(More)
